Abstract:

A numerical reconstruction is implemented according to a combination of MUSCL(Monotonic Upstream-Centered Scheme for Conservation Laws) and THINC(Tangent of Hyperbola for Interface Capturing) methods. And a new constructed solver is derived by the combination. The main principle of this reconstruction solver is to keep the variation diminishing of every cell boundary to a low level. And a BVD(Boundary Variation Diminishing) principle is set according to the left and right boundary states in MUSCL method, as well as which in THINC methods. To obey the BVD principle, an alternative choice between the MUSCL and THINC is needed here. Thanks to the BVD solver, the discontinuous section becomes smooth and the oscillation is significantly controlled. The numerical performance of BVD reconstruction is then tested by 1D and 2D numerical examples.

Key words: boundary variation diminishing(BVD) reconstruction, Mie-Grüneisen mixture model, monotonic upstream-centered scheme for conservation laws, tangent of hyperbola for interface capturing
